2 Claims. (Cl,- 210- 29) This invention relates generally tothe chemical treatment of swimming pools and the like and, more'particularly, to a certain new and useful improvement in means for subjecting the pool-water to chemical treatment for the destruction of fungus growths and the like.

' Public swimming-pools and the like require, as is commonly known, substantially constant vigilance for their sanitary maintenancef And one of the frequent causes of an unsanitary condition in a pool necessitating complete removal for sanitary maintenance isa' fungus' growth known as algae. My presentinvention hashencejor its chief object the provision of means in the form of'a perforated chemical container 'uniquely' constructed for convenient travel in'the pool foreffecting destruction of fungus growths of the type mentioned and other impurities.

My invention has for further objects the pmvision, as a new article of manufacture, of a rugged, durable, compact chemicalcarrier suit able for immersion in and movement through the pool-water and the like for germicidalt'reatment, which is unaffected byeither the chemical members or the pool-water itself, which is siniple and inexpensive in construction and may be 'very readily andeasily usable with a'lfninim-um of labor, whichis uniquely arranged -for'forcibly circulating pool-water through the mass of chemicals during movement or travel through the pool w ater for'eflectively and positively introducing thereinto .a quantity ofthe treating chemical sufficient to produce a satisfact ory de structive effect, and which is highlvefiicientein the performance of. itsstatedf functions And with the above and otherfobj'ects in view, my invention resides in the novel features of form, construction, arrangement, andjcombina tion of parts presently described, and pointedout' in the claims.

In the accompanying drawing:v r Figure l is aperspective view of )a reagentI carrier constructed in'accordance with; and em: bodying my present invention; 4 Figure 2 is an enlarged fragmentary'front elavational view of'the carrier; I I

Figure 3 is a transverse sectional view of the carrier takenapproximately along the line 3-3, Figure 2;

Figure 4 is a similar view of the carrier with its closure-lid in place;

Figure 5 is a reduced diagrammatic view illustrating the disposition and travel-movement of h the carrier for the purifying or germiciding treatment of a'swimmingpool; and

Figures 6 and 7 are reduced top plan and dia'-' grammatic views, respectively,' of the carrier equipped with a modified form of handle-structure for facilitating treatment of the water adjacent the vertical side walls of the pool.

Referring now in more detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, the car rier; generally designated A, is in the form of a carriage comprising a pair of suitably rigid parallel end walls' l preferably of rectangular con:

tour and having relatively wide top, side, and,

bottom marginal faces 2,3, 4, respectively. Up"- on their outerface, each of the end walls I is preferably integrally provided with an outward-' ly' projecting depending boss or'enlargement 5 recessed in its under face in the provision of spaced flanges 6 providing an open-ended i nverte'ci 'u shaped channel or way 1. Formed preferably integrally with, and extending be tween, theopposed inner faces of the end-walls 'l, isavertically disposed cross wall 8 preferably unitarily connecting the .end'wall members Lin suitable spaced relation, the wall8 being pref-'- erably disposed midway between the marginal side faces 3 and'having avertical dimensionxsub-j" stantially equal to the vertical dimension of the endrwalls l". Suitably journale'd for rotation and preferably disposed in tandem relation in.each of the ways vI, are respective pairs 'of, suitably spaced rollers 9,all as best seen in Figures 1, 2, and;.3t'and for: purposes presently :ruu appear--.

The so-connected' end walls I and their sup porting rollers 9 provide a vrollable frame; and suitably fixed at its opposed transverse margins, as by means ofscrews In or the like, upon the side andbottom faces 3, 4, of, and extendinghore; izontally between, the end walls I, is a U-shaped troughelike member I I formed preferably of anysuitable foraminous or reticulated sheet metallic material'providing a multitude of openings or perforations; At is upper horizontally extending'margins, the perforated. or apertured wall; member *II is provided with curled-over beads |2,,:the upper peripheral portions of. which lie the distance between the outer faces of the end wall members i and a Width substantially equal to the distance between the outer faces of the vertically disposed sections or legs of the U- shaped wall-member II for abutment upon its under face with the beads l2 in the formation of two basket-like compartments a, a, separated by the preferably solid imperforate vertically disposed connecting wall-member 8, all as best seen in Figure 3 and for purposes presently fully appearing.

Adapted for snugly fitting removablyupon and over the top wall or plate I4, is an imperforate closure lid B stamped or otherwise suitably formed of sheet metal and including a top panel l5 provided with a narrow depending. marginal flange [6, all as best seen in Figure 4.

Thus the carrier includes a pair of containers j each having perforated front, top, and bottom walls and imperforate end and rear walls, the wall 8 being common to both containers.

Fixed in, and projecting from, the out-er face of each of the end walls I, are eyes [1, detachably engaged with which are suitable hooks I8 conventionally fixed upon the opposite ends of a suitable length of pull chain is, in turn, conventionally looped through the end-eye 20 of a conventional draw rope 2 I.

In substitution of the hooks I85 and the chain i9, isa suitably elongated, shaft 22- provided at its one end with a yoke, 23 having outwardly diverging arms 24', in turn, provided. at their ends with forwardly projecting parallel sections 25 bent over at their ends for engagement in the eyes I I, all as best seen in Figure 6. I 1

. It should be noted that all of the several parts of the carrier or carriage A should be fabricated from bronze, stainless steel, orotherchemicalresistant materials so as to be substantially unaffected by the chemical or agents employed in the. pool-treatment. For likereason, the chain l9 and yoke 23 should also be constructed of chemical-resistant materials. Since, however, both the chain l9 and yoke 23 are generally of sufilcient size, the drag rope il -and the handle 22- are sufficiently removed from the region of the agent carrier itself, so that'the: concentration of the carried chemical is sufficiently dilute as to be ineffective.

In'use, the lid B and top plate [5 are removed from the carrier A and the two compartment's a, a, filled with crystalline copper sulphate or other suitable bactericidal agent. The top plate I4 and lid B are thereupon replaced,

and the carrier A suitably disposed in, and pulled by means of the rope 2|. and chain lsralong the bottom of, the pool, as shown in Figure 5.' As the carrier A is drawn in one direction, the water of the pool will flow into'the chamber a and be deflected by the wall 8 downwardly, causing the water forcibly to circulate through the quantity of copper sulphate or other treating material, as shown by the arrow in Figure 4. At the same time, the forward movement of the carrier A and particularly the wall 8 thereof produces a condition in the nature of a vacuum in thechamber a, which induces an upward an'drearward circulatory flow of thepool-water, thereby promoting intimate chemical-agent treating contact with the water and materially facilitating the interin'itially mixing and. solution therein of a suitable quantity of the chemical-agent material.

In the region of the sump of the pool, there is an increased tendency to algae growth and con- 5 centration of bacteria, making it desirable that increased amounts of the treating agent be introduced into the water in this region. To effect this purpose, the lid B may be removed and the carrier A pulled back and forth across the grating over the sump. In such case, the water flows not only downwardly through the compartments .a, a, but also upwardly, as indicated by the arrows in Figure 3.

In order to inhibit algae growth along the side walls of the swimming pool, the chain I9 is preferably detached from the eyes I! and the handle '22 substituted, so that the carrier A, with its rollers or wheels 9 presented against the side faces of the pool, as shown in Figure 7, may be rolled up and down with a vertical motion for effectively treating the water in this region. I

The carrier A has been found exceedingly emcient in the performance of its intended functions, and it should be understood that changes and modifications in the form, construction, at-

rangement, and combination of the several parts of the structure may be made and substituted for those herein shown and described without departing from the nature and principle of myinvention.

Having thus described my invention, what I claim. and desire to secure by Letters Patent is:
